Question

A rectangular hall 12m long and 10m broad is surrounded by a verandah, 2m wide. Find the area of the verandah.

a. 105m2

b. 104m2

c. 89m2

d. 123m2

Answer 1

Area of Hall = 12*10=120

Area of Hall with veranda=14*12=168

Area of veranda=168-120=48m2

Answer 2

Step 1: Find the area of the hall

Area of the hall = Length x Breadth

Area of the hall = 12 x 10 = 120 m²

Step 2: Find the length and breadth of the hall and verandah:

Length of the hall and the verandah = 12 + 2 + 2 = 18 m

Breadth of the ball and the verandah = 10 + 2 + 2 = 14 m

Step 3: Find the area of the hall and verandah:

Area of the hall and verandah =  Length x Breadth

Area of the hall and verandah =  18 x 14 = 252 m²

Step 4: Find the area of the verandah:

Area of the verandah = 252 - 120 = 132 m²

Answer: (d) 132 m²
